A coupling system comprising a first androgynous coupler and a second androgynous coupler. The first androgynous coupler comprises a first male coupling section having a first recess extending radially and a first female coupling section comprising a first blocking element and a first positioning element. The second androgynous coupler comprises a second male coupling section having a second recess extending radially, where the second male coupling section is configured to form-fit with the first female coupling section. When the second male coupling section is form-fit with the first female coupling section, axial movement of the first positioning element causes the first blocking element to move radially into the second recess to couple the first androgynous coupler to the second androgynous coupler.

In order to produce a circuit board plug connector in which the advantages of hermaphroditic plug connectors are combined with the advantages of conventional plug connectors, a contact carrier is equipped with both plug contacts of a first type and plug contacts of a second type in equal numbers. Advantageously, the plug contacts of the first type are designed as “male” contacts (blade contacts) and the plug contacts of the second type are designed as “female” contacts (fork contacts) and can be plugged into one another in principle.

A lamp with hybrid connector is provided, which includes a lamp tube and two lamp caps. The lamp caps are disposed at the two ends of the lamp tube respectively. Each of the lamp caps includes an end surface, two first connection structures and two second connection structure. The end surface has a central point. The first connection structures are disposed on the end surface and are arranged to be symmetrical, about the central point, to each other. The second connection structures are corresponding to the first connection structures. The second connection structures are disposed on the end surface and are arranged to be symmetrical, about the central point, to each other. Since each of the lamp caps has a symmetrical connection structure, any one of the two ends of the lamp tube can be connected to another lamp tube in series.

An electrical connector is provided that includes a plurality of electric cables. A first adapter is configured to receive the electrical cables. The first adapter protects the electrical cables and allows for an electrical connection between the electrical cables and a plurality of electrical pins. A second adapter is coupled to the first adapter. The second adapter allows for an electrical connection between the electrical pins and a plurality of electrical terminals. A cable kit is provided that is at least partially housed within the second adapter. The cable kit has a plurality of projections extending therefrom. An insulator body is coupled to the second adapter. The insulator body includes a plurality of openings. Each of the openings has a tapered end portion configured to receive a corresponding one of the plurality of projections of the cable kit to form a mechanical seal with the cable kit.

An electrical connector includes a housing having a hermaphroditic mating interface configured to be mated with a mating electrical connector having an identical mating interface. The housing a contact shroud at the mating end with openings at the front. A contact assembly is received in the contact cavity with mating ends of contacts aligned with corresponding openings and defining a hermaphroditic contact interface. The electrical connector includes a retractable cover located at the contact shroud to close the openings that is movable relative to the housing between a closed position and an open position. A cover actuator is coupled to the housing including a pusher and an actuation element operably coupled to the retractable cover. The pusher is configured to interface with a complimentary actuation element of the mating electrical connector to actuate a retractable cover of the mating electrical connector.

A connector part includes: a plurality of hermaphroditic contact elements for contacting associated hermaphroditic contact elements of a mating connector part, each of the plurality of hermaphroditic contact elements having a body, a first contact lug extending from the body along a first direction, and a second contact lug extending from the body along the first direction. The first contact lug and the second contact lug are offset from each other along a second direction that extends transversely to the first direction, and along a third direction that extends transversely to the first direction and transversely to the second direction. The connector part has, for each hermaphroditic contact element, a hermaphroditic contact element mirror-inverted to a first mirror plane spanned by the first direction and the third direction and a hermaphroditic contact element mirror-inverted to a second mirror plane spanned by the first direction and the second direction.
